Add-A-Valve® Video

Watching the Add-A-Valve installation video is REQUIRED to properly install the Add-A-Valve® device.

There are two types of Add-A-Valve®:

Single Stem for sizes 1/2" - 1"

Double Stem for sizes 1-1/4" - 2"

Installation for both types are the same until you reach step 10. If you are installing a double stem Add-A-Valve, you must utilize a second person. Pay close attention to step 10b.
